Abstract: PURPOSE:To enable small diameter of a supporting member and to execute laser quenching to inner peripheral face in a small diameter hole by constituting the titled working head so as to execute cooling of a bent mirror irradiating especially the inner face of hole bored in a work by using a heat pipe. CONSTITUTION:After positioning the lower end part of the mirror supporting member 19 by inserting into the hole H in the work W, the laser beam LB is generated 5 and radiated to the bent mirror 17 from upper direction through optical system in the working head 15. Therefore, the beam LB is horizontally reflected to irradiate the inner peripheral face of the above hole H. Then, at the time of rotating inner cylindrical member 31, etc., by working a servomotor 37, the supporting member 19 is rotated around the optical axis and the beam LB is made to one round while irradiating to the inner peripheral face in the hole H. In this result, the laser quenching can be executed to the inner peripheral face in the hole H. During this operation, temp. of the mirror 17 tends to raises, but as the heat of the mirror 17 is transferred directly to the heat pipe 47 and to the heat pipe 47 through a base seat 45, the cooling of the mirror 17 can be effectively executed.

Title: Transfer paper for electrophotography
Inventor: KARAMI YUUSUKE
IPC: G03G7/00
Filed: 1983-09-14
Abstract: PURPOSE:To enable suppression of generation of paper dust by deciding the circumferential length on the cut surface of transfer paper at a specific ratio or below with respect to the linear distance of the cut surface. CONSTITUTION:If many sheets of transfer paper 6 are cut by a rotary cutter or a guillotine cutter having a worn edge, the cut surface 7 of the paper 6 has large ruggedness which leads to generation of a large amt. of paper dust. If a large amt. of the paper dust is generated, the flow of an image, defective cleaning, etc. are induced by sticking of the paper dust to a photosensitive drum. The generation of the paper dust is extremely little in this case when the length tracing actually a cutting curve 7, that is, the length B when the curve 7 is extended to a straight line 7' is <=1.2 with respect to the linear distance A of the cut surface of the transfer paper 6.

Abstract: PURPOSE:To offer an element isolation film which is free from a bird's beak by providing the following: a groove formed in a silicon semiconductor substrate of one conductivity type; an oxide film formed selectively on the bottom of the groove, an oxide film which has been formed uniformly around the groove and whose thickness is smaller than that of the oxide film on the bottom of the groove; non-single-crystal silicon filled into the groove; and an oxide film formed on the surface of the non-single-crystal silicon. CONSTITUTION:A thickness of a groove formed inside a silicon substrate 5 is 0.8mum and its width is 0.5mum; a thickness of a selective oxide film 1 formed on its bottom is 0.25mum; a thickness of an oxide film 2 formed on sidewalls of the groove is 0.05mum. Polycrystalline Si 3 is filled into the groove; the surface of the polycrystalline Si 3 is oxidized. Non-single-crystal Si such as amorphous Si may be used instead of polycrystalline Si. The selective oxide film 1 on the bottom of the groove is formed by pyrooxidation and an end point of an oxidation process is set near a point where a bird's beak reaches the sidewalls of the groove; as a result, a stress from an Si3N4 film by oxidation is not caused, and a residual stress during a dry etching operation attains a nearly negligible degree.

Title: Optical variable attenuator
Inventor: KOGA MASABUMI
IPC: G02F1/313
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To obtain an optical variable attenuator which is small in size, is strong to mechanical vibration and temp. change and is electrically controllable by using Y-branched waveguides where the waveguide refractive index is changed by a thermo-optical effect, changing the refractive index of the one waveguide thereof and varying the light intensity to be coupled to the output waveguide. SOLUTION: Heater resistors 2-1, 2-2 are deposited by evaporation in the branching parts of the Y-branched waveguides formed of a polymer material. The light inputted from the optical waveguide 1-0 is outputted to the optical waveguides 1-1, 1-2. The light intensity outputted to the respective optical waveguides changes according to the impressed state of the heat in the branching parts. Namely, when the current to be passed to the heater resistor 2-2 is successively increased, the refractive index in the branching parts to the optical waveguide 1-2 increases and the symmetricalness of the branching parts collapse, thereby increasing the coupling rate to the optical waveguide 1-1. The optical waveguide 1-1 is used as the output waveguide and the optical waveguide 1-2 is used as a dummy waveguide not used as the optical variable attenuator.
